This will copy the image from HD0 to HD1 for instance, BUT, HD1 must to be equal or larger in size to HD0. You won't be able to use any unused portion if larger..... This would be a typical command for dd: # dd if=/dev/ad0 of=/dev/ad1 bs=8192 You can experiment with the "bs" size. I use 102400 for example and cuts the backup time in half. Best regards, Jack L.
